BOX SEAL.

Application filed May 20, 1925. Serial No. 31,602.

This invention relates to certain improvements in box seals and moreparticularly to that type in which the sealing device is a metal plateor strap with portions adapted to be driven into the wood of twoadjoining walls of a wooden case for connecting them and preventingseparation without mutilation of the seal or case. I

As one important object of my invention, I so design the parts that eachpart is locked in place by nails which pass through the other parts andcannot be removed. In its preferred form, the seal in cludes two partswhich engage with the outer surfaces of two adjoining walls of the boxor other packing case and each of these parts has a perforated flangeport-ion adapted to be driven into the wall of the box and held thereinby a nail driven through the box wall, the other part and theperforation.

In the accompanying drawing, I have allustrated'two embodiments of myinvention. In these drawings, 1 V

Figure 1 is a perspective view of one type of shipping case with whichmy improved box seals may be employed,

Figure 2 is a transverse section through the corner of a box with theseal in position,

Figure 3 is a perspective view of one part of the seal shown in Figure2,

Figure 4 is a perspective view of the other part and Figure 5 is aperspective view of a nail which maybe employed for connecting the partsand holdingthem in position.

I have illustrated my invention as applied to a shipping case havingside walls A, end walls B, a bottom and top' C. as illustrated each endwall has a marginal frame formed of four cleats D, secured to the outersurface thereof. Thus no one of'the'boards forming the end walls, can beremoved without first removing one of the cleats formin this end frame.The box at each C) end has a second set of cleats E, whichare secured tothe sides, top and bottom, and

.which are connected together at their ends so as to form a secondframe. The cleats E of this frame prevent the removal of any one of theside, top or bottom boards without first removing one of these cleats.The outer edges of one set of cleats overlap the adjacent edges of theother set. For instance the cleats D may have their outer edgesterminating flush with the outer sides of the top, bottom and sidewalls, while the cleats E project beyond said walls and cover the outeredges of the cleat D. I provide seals for connecting each cleat Eto itsadjacent c'leat D so that none of the cleats and none of the boards ofany wall ofthe box can be removed without first removing or breaking theseal.

In the specific form of seal shown in Figures 2, 3 and l, the bodyportion includes two parts or sections adapted to be-con- V nected tothe box in succession. One part is shown particularly in Figure 3, andincludes a plate 10, a pair of end or terminal flanges 11 and 12, andside flanges 13 which are preferablyserrated so as to form a series ofshort sharp pointed teeth. The plate '10 is provided witha'nail hole 14which may be of a shape-and size depending upon the character of thematte be employed. For instance, if it is desired to uses nail 15, outfrom sheetinetal with a flat, thin head, such as shown in Figure 5, thenail hole 14: may be in the form of a slot. If a roundnail is to beemployed, thenail hole may be'round. To accommodate either lrind, thenail hole may be as shown in Figure 3, that is, in the form of a slotwith an en- ;larged central portion adapted to receive either shape ortype of nail.

The flange 12 has a similar nail hole 16 in alignment with this is anail hole 16 in tl'ieflange 11. The flange 12 also has a slot 17betweenfthe nail hole 16 and the plate 10 for receiving "a flange onthe: other part of the seal as hereinafter pointed out.

In F igure there is shown the second part of the seal, which includes aplate portion 18 with end or terminalflanges "l9 and 20 and serratededgeflanges 21. The flange 19 is of such size that it may ente'r'theslot 17 of the part shown in Figure 8 and this flange has a nail hole 22which will come into registry with the nail hole 1 1- wh'en the flange19 is extended through the slot 17.

The flange 20 has a nail hole-23 in registry with the'nailhole 2'2. V

. In applying the seal shown in 'Figures 3 and 4c, of a box ease, thepart shown in from being drawn out of the wood.

Afterthe plate 10 has been placed in position and securedby the nail 15,the other part is applied. The flange 19 is inserted through the slot 17and the part is driven into position by forcing the flanges 19 and 20into the wood. -The Y plate 18 extends across the joint betweent-hecleats D and E,

the flange 19 entering the cleat E and the flange 20 entering the cleatD. The serrated flanges 21 are drivenvinto the wood along the sideedgesof the flange-12 so as to pre vent any one from forcing, a tool beneaththe plate 18 to pry the latter outwardly. .After this part has beenforced into position, a

second nail 15 which may be similar to the nail 15 is driven through thealigned nail holes 1 1, 22 and 23. The head of the: nail is forced inuntil it is flush with the outer surface of the plate 10, so that thenail cannot be engaged by pliers: or other toolto withdraw it. The headof the nail 15 is protected by the plate 18 and the plate 18 isprevented from being withdrawn by the nail 15 which. passes through bothterminal flanges of the plate 18. Thus when the parts are in positionthe cleats Dand E are connected and the connecting part is locked by'anail which is positioned by the holelt.

I am aware that it has been proposedto use box seals somewhat similar tothat shown in Figure 4, but when such box seals are used alone, it isdiificult to so position the nail that it will pass through theapertures of both flanges. In'my improved'con'struction, the position ofthe nail is determined by the hole lw-hich is alignedwith the nail holes22 and 23. If one uses only theparts shown in Figure 1, the head of theretaining nail will be in thewood of the cleat E g and can readily beremovedwith an ordinary nail puller, unless some special form of nail beprovided. In my improved construction, I may employ any ordinary form ofnail if the head is of such cha'racterthat it may fit into a countersunknail hole- Various forms of my invention may be designed within thescope of the appended claim. Iv do not wish to limit the use of the-which are to be driven into the wood will lie in a plane lengthwise ofthe grain of the wood, rather than across the grain.

It is preferable in forming the nail holes 16 and 14;, that the metal beforced up to form a short, outwardly projecting tube on the outersurface of theplate. This serves as a guide for the nail so thatthelatter is more accurately directed. to the holes in the flangesembedded in the wood therebeneath. Upon hammering the nail into positionthe metal forming this short upwardly or outwardly projecting tube, maybe hammered down over the head of the nail as an additional protectionagainst withdrawal of the nail.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is: a

A box seal including a pair of members,

' one including a plate portion adapted to engage with a side ,of thebox adjacent to the corner, and provided with a slot and a nail hole,the slot being disposed between the nail hole and the edge of the plateat the box corner, a second plate portion integral with the firstmentioned'plate portion and dis posed at rightangles thereto, andadapted toengage'with an adjacent side of the box and provided with anailhole and a flange integral with the second mentioned plate portionand disposed at right angles thereto and parallel to the first mentionedplate portion, said flange having a nail hole in alignment with the nailhole of the first mentioned plate portion whereby said member may besecured to thebox by a nail driven through the nail hole of the firstmen tioned plate portion, and thereby guided to the nail hole ofsaidflange, and the other member. including a plate portion adapted tobe superposed on the first mentioned plate portion of the other member,and including I a pair of opposed parallel flanges having nail holes,and adapted to be driven intothe box with one flange extending throughsaid slot to bring the nail holes of said flanges into aligmnent withthe nail hole of the sec ond mentioned plate portion.
